The U.S. tax system is progressive — meaning higher income is taxed at higher rates, but only the income within each bracket, not your entire income. Understanding how tax brackets work helps you estimate what you owe, evaluate financial decisions, and avoid the common misconception that earning more can somehow cost you money overall. This page explains how brackets work, what the 2025 rates are, and how the standard deduction fits in.
How Tax Brackets Actually Work
A common misunderstanding: if you move into a higher tax bracket, all of your income gets taxed at the higher rate. That is not how it works. Each bracket applies only to the income that falls within it. The higher rate kicks in only on the dollars above the threshold — not on everything you earned.
For example: a single filer with $60,000 in taxable income for 2025 pays 10% on the first $11,925, 12% on income from $11,926 to $48,475, and 22% only on the remaining income from $48,476 to $60,000. The effective rate — total tax divided by total income — is well below 22%.
2025 Tax Brackets — Single Filers
The 2025 federal income tax brackets for single filers: 10% on the first $11,925 of taxable income; 12% from $11,926 to $48,475; 22% from $48,476 to $103,350; 24% from $103,351 to $197,300; 32% from $197,301 to $250,525; 35% from $250,526 to $626,350; 37% above $626,350. These thresholds are adjusted each year for inflation.
2025 Tax Brackets — Married Filing Jointly
For married couples filing jointly, the 2025 brackets are: 10% on the first $23,850; 12% from $23,851 to $96,950; 22% from $96,951 to $206,700; 24% from $206,701 to $394,600; 32% from $394,601 to $501,050; 35% from $501,051 to $751,600; 37% above $751,600. The married filing jointly thresholds are roughly double the single thresholds in the lower brackets.
Marginal Rate vs. Effective Rate
Your marginal rate is the rate that applies to your last dollar of income — the bracket you are “in.” Your effective rate is the average rate on all your income — total tax divided by total taxable income. These are different numbers. Someone in the 22% bracket does not pay 22% on everything; their effective rate is lower because the first dollars were taxed at 10% and 12%. Knowing both helps you understand your actual tax burden.
Taxable Income vs. Gross Income
Brackets apply to taxable income, not gross income. Taxable income is what remains after subtracting the standard deduction (or itemized deductions) and any above-the-line adjustments such as IRA contributions or student loan interest. For most people, the standard deduction alone reduces taxable income significantly — for 2025, it is $15,000 for single filers and $30,000 for married couples filing jointly.
The Senior Standard Deduction
If you are 65 or older, you qualify for a higher standard deduction. For 2025, single filers who are 65 or older can deduct an additional $2,000 on top of the base $15,000, for a total of $17,000. Married couples each get an extra $1,600 per qualifying spouse — so a couple where both spouses are 65 or older deducts $33,200. This directly reduces your taxable income and, in turn, your tax bracket placement.
Other Income Types and Rates
Not all income is taxed at ordinary bracket rates. Long-term capital gains — profits from selling assets held longer than one year, including stocks and real estate — are taxed at lower preferred rates of 0%, 15%, or 20% depending on income. Qualified dividends are taxed at the same rates. Social Security benefits may be partially taxable depending on your combined income. These distinctions can meaningfully affect your overall tax picture.
